Selenium test to create users.

Trying to setup a selenium test and I am having some issue. This is in the create user process.it's working very well until I get to the click on the create user button. the button is disabled, the fields are valid. If I stop the script and touch the user field it will then work.

the javascript is not seeing the field value is set. I can see notes that your using selenium for your testing so I would expect you have seen this and know what might be required.

This is just initial code that I convert to java later and automate, but for now I just want it to work so I know what is required.
